as a former squid, most of the ships stationed in Japan had this effect. the wave action pushes the Skin of the ship into the ribs/internal bracing. we called it "waffle hull"  from the obvious reference.  if your ship encounters Heavy seas for a prolonged period of time = waffle hull.

Battleships, in fact Naval vessels of all kinds suffer dings, dents and bashes.  When HMS Glamorgan had a catastrophic boiler room fire they had no steam to power the fire pumps.  So they sealed off the burning boiler room and starved the fire of air.  The resulting vacuum caused the hull to suck inwards by 6 inches on each side.  They never tried to get the dents out so she spent the last 10 years of her life with a wonderful wave shape down her length. I was in the Royal Navy at the time and saw her like this.

You're amazing Ryback, its a shame you're not cooking for us.

IMO the "oil canning" on the hull is stunning and brings ship to life. Kudos! Look forward to seeing the finished and weathered Missouri.

now that looks nice I would never have the guts to take a scraper to such an expensive kit.  I switched over to Acrylic paint 2 years ago and i love it and so does the wife, so much less smell and i love how fast it drys.

Wave action,warping from welds, and being pushed by tugs for 70+years.
She, the NJ, and the Iowa were usually berthed at the secondary carrier piers(2&3) near us in Norfolk back in the mid-late 80s.
I was stationed aboard Concord AFS5, we were always berthed at pier 4 northside whenever we weren't overseas during our  Med Cruises.
We served with the Big Mo, Iowa,NJ, America, JFK, Forrestal battle groups from 86-89.
We were present the day when the Iowa had her #2 turrent incident.
I have yet to visit the Iowa again, even tho I only live an hour away in SoCal.

I’m not the kind of model builder who builds for realism. With some of the models I’ve build, I have incorporated some painting techniques so the model looks weathered but that’s about it. That said, what you’ve  done is next lvl in terms of weathering and realism; at least from my view point. It looks great! It speak to your creativity and sets you apart from average Joe’s like me who would have just primed and painted the hull straight up! Thanks for sharing. I was genuinely inspired.

for the black water line stripe i use auto pin stripping.

The "oil canning" is a good creative touch! Some oil canning on ship hills is when welding was done on the outside before the inside is completely finished.

(NOTE: Nigel at "Nigel's Modeling Bench" on YT did the dent thing on his Missouri hull as well). I pointed this out in the first vid, but the shp's hull experienced "dishing," which is what the dents on a Navy ship's hull are known as. "Tin-canning" is more related to Navy destroyers, more familiarly called "tin cans" by Navy folks. They're also known as "small boys" or -- in WWII, when it came to destroyer escorts (DEs) on North Atlantic convoy duty -- "grayhounds." Smalls boys (DDs, DEs, even fast frigates or FFs) were thin-hulled and lightweight, but they could be turned out amazingly quickly. Not so with battleships. As I found out when I was one of many, many who helped restore the Mighty Mo to her WWII glory back in '98, much of the dishing occurred over the many decades of her life, and not necessarily from her WWII service particularly, which was of relatively limited duration, except for her combat actions, of course. Any time Navy ships warp or kedge into and out of a pier ("warping" and "kedging" are more sailing-era terms but they're very descriptive) there's likely to be dishing as a result... expect when some dumb junior officer happens to ding the ship when he's parking it. That's totally on him, then. ;-)

Looks amazing and definitely makes a difference in the end. A couple techniques that have helped me with the hull dishing in the past is to prime it with a coat or two and then start on the hull dishing with a curved scraper. Scraping into the primer has really helped with a softer effect instead of going right into pure plastic.  I used one of those extra soft pillows with the ripped up foam pieces in it to rest the hull on and it let me position/prop up the hull at all different angles which made it a lot easier to work on. Definitely helps with the scraping when it’s not totally parallel to the table. Looks 👍

The dents look great.  They are the results of the wave actions on the plates between the vertical and horizontal bulkhead bracing.

the beginning music reminds me of Breaking Benjamin or Incubus lol something like that

First time watching a modelling video and I never realised the attention to detail with putting the dents in.........dedication! 👍🏼

Ok.. every US warship I visited  looked like you could kick your foot right thru the hull... you are correct, the hulls of US warships are dented very much so and very noticeable.  I am impressed with your bold attempt to create that realism to your kit....BRAVO ZULU!

The tin canning came out great, it's a nice touch that you don't see much of. I do agree with the bigger scales did some more detail on the hulls. There is a sight, Scale Model Workshop Paul Budzik . He dose lots of videos on panel lines, hull plates and detailing. Not that you need the help.

Didn't know Benny Hill did model building ... :) Thanks for sharing, nice tips.

I wrote my name on the bottom of the keel when we were in dry dock once. Your model is looking fantastic.

You warned us advanced that it would take time between episodes..I am happily surprised it was this fast already

You are doing a really fine detail job on that ship. I went to see the Arizona Memorial in Hawaii . The Missouri was berthed  further down and you are point with the oil canning. Job well done. I have scene this effect on modern commercial ships at the Port of Houston Bay Port Facility when I was on patrol as a police officer.
